An Indiana mother has claimed that her home in Indiana is demon-possessed and her children have been possessed doing shocking and unbelievable things.

Now court documents, police testimony and an audio recording may prove her story to be 100% true.

Latoya Ammons claims all three of her children showed signs of being possessed, including “evil” smiles and strangely deep voices, the Indianapolis Star reports.

The mother says she also witnessed her 12-year-old daughter levitating in their Gary, Indiana home.

Gary police Capt. Charles Austin told the Star that he is a “believer” after making several visits to the home and interviewing witnesses. He first thought the family was making stories up as part of a get-rich-quick scheme.

Ammons’ story is backed up by her mother, Rosa Campbell, who has lived in the house, witnessing the strange behavior.

Moreover, in 2012, child protective services in Indiana was contacted to investigate the mother for possible child abuse or mental illness. A psychiatrist reportedly evaluated Ammons and determined she was not mentally ill.

A family case manager reportedly interviewed the family and witnessed a number of strange occurrences. Valerie Washington confirmed that she witnessed the youngest boy growling before his eyes rolled back in his head.

Washington also claimed she saw the 9-year-old boy flash a “weird grin” and then walk backward up a wall to the ceiling. Her account was corroborated by a nurse.

“There’s no way he could’ve done that,” the nurse told the Star.

After being sent to investigate Ammons, Washington concluded that an “evil influence” might be affecting the family.

While authorities were recording inside the home’s basement, they reportedly picked up something hair-raising and unexpected — a voice that clearly whispered, “Hey.”

According to The Daily Mail, none of the officers uttered the word while they were touring the home in spring of 2012. Gary police captain Charles Austin, 62, was so stirred by the experience that he’s speaking out, proclaiming that that the basement is “a portal to hell.”

“Everyone of us who was there that day in the basement and who saw what we saw, went through what we went through after … we all think the same, we all call it the same. That bit of dirt is a portal to hell,” he told Daily Mail.
